AUTOMOBILE-WHEEL ATTACHMENT.

Specification of Letters Patent.

Patented Mar. 29, 1921.

Application filed November 27, 1920. Serial No. 426,721.

To all whom it may concern:

Be it known that we, HENRY ll. Knuui and ADAM H. Gnosz, citizens of the United States residing at New Orleans, in the eonnty of (lrle 11s and State of Louisiana, have invented new and useful, Improvements in AutomobilelVheel Attachments, of whichv the following is a specification.

The object of our present invention is the provision of a simple, inexpensive, and easily applied automobile wheel attachment, :alculated to impart to a wheel the capacity of exl'rieatinp; itself promptly from mud holes ruts and soft depressions in roads.

To the attainment of the foregoing, the invention consists in the i1111')l0it)l1llll; as hereinafter described and. definitely claimed.

In the accompanying drawings, forming part hereof:

Figure l is a view showing our novel at taolnnent as properly applied to a portion of an automobile wheel.

Fig. 2 is a transverse section of the same.

Fig. is a view showing}; the tread portion of the attachment body in plan.

Similar numerals of re'lprence designate corresponding parts in all of the views of the drawings.

The automobile whee]. includes a tire 1., a folly 2, and a spoke 3 and is otherwise of the ordinary well known construction.

Among other elements our novel attachment comprises a U-shaped body 4; which is preferably of cast metal and is made quite heavy so as to withstand hard usage. The said body 4 is adapted to be arrangedv in straddling relation on the tire and folly as host shown in Fig. 2; and it is character-- ized by a transversely ribbed or corrugated tread portion 5 and by side portions 6 in which are apertures 7.

In addition to the body 4lthe attachn'leut ron'i prises cross bars 8. detaohahly eonnorrted to the side portion (3 of the body and a (lapted to be arranged. at opposite sides of a spoke of the wheel. It is desirable to quickly and easily disconnect the cross bars 8 from the side portions 6 of the body. and therefore we prefer to employ the c0nstruetion best shown in Fig. l for the connection of the bars 8 t0 the body portions 6. According to the said construction the outwardly extended end portions of the bars 6 are provided with apertures 9, and hooks 1.0 are pivoted at ll to the outer sides of the portions 6 and are adapted to be swung; into and out of the apertures 9. lldanifestly when the hooks ll) are positioned as shown in Fig. 1 the bars 8 will he securely though. detachably connected to the body. l Vhcn, however, the hooks ill are swun out of the said apertures 9, the bars 8 may he slipped endwise out of eiunipeniei'it with the portions 6 so as to permit of the bod being; readily disassociated from the tire and the folly.

It will be apparent from the foregoing that our novel, attaelnnent is susceptible of quick and easy application to an automobile wheel; also, that when the attaelnnimt is applieo as shown in ll" l. 2 and 3 it will lend to the wheel the ability to extricate itself from a mud hole or any other soft depression in a road. This will he hotter understood when it is: "tated that when the wheel. is powerfully tinned, the attachment body will take secure hold of the 'rornd and-will afford ample traotion for the entrication of the wheel from a soft (ilepression or from any other depression of considerable depth.

l-lavinp; described our inveutioin what we elaim and desire to secure by Letters-Patent, is

on aiu'oinol'iile wheel attachment eon prising a Ushaped hody adapted to he an ranged in SlLlTllldlllliJf relation on a wheel tire and folly and having; a trausvorsely-iiblied tread portion and also having side portions with transverse apertures, transverse bars extending; between said side portions and removahlv arranged in and extending outwardlydaevond said apertures and adaptel'l to rest at opposite sides of a spoke of a wheel and haying apertures in their extended portions, and hooks pivoted to the side portions of the body and arranged to enter said apcr turos of the transverse bar, and dctachably fasten the bars to the hody.

In testimony whereof, we allix our natures.

HENRY R. KLARE. ADAM H. GROSZ.
